Novel assembled buckling-restrained brace

Abstract

The invention discloses a novel assembled buckling-restrained brace. The novel assembled buckling-restrained brace comprises an outer connecting plate and an anti-instability steel pipe, the outer connecting plate is fixedly connected with a force transmission round pipe, the force transmission round pipe is nested in the anti-instability steel pipe, the end, away from the outer connecting plate,of the force transmission round pipe is connected with a round connecting end plate in a welded mode, and the other end of the round connecting end plate is connected with a dumbbell-shaped energy consumption cone steel bar in a friction welded mode, cross stiffening ribs are embedded in the ends, away from the connecting plates, of the force transmission round pipes, the circle centers of the force transmission outer connecting plates, the circle centers of the anti-instability steel pipes, the circle connecting end plates, the circle centers of the dumbbell-shaped energy dissipation cone steel bars, the circle centers of the cross stiffening ribs and the circle centers of the force transmission round pipes are located on the same axis, gaps of 2 mm are formed in the force transmission round pipes and the anti-instability steel pipes, and the cross stiffening rib is connected with the circular connecting end plate in a welding manner and is not fixedly connected with the force transfer circular pipe. The structure is convenient to machine, easy to install, environmentally friendly, capable of improving production efficiency, stable in structural form and capable of remarkably enhancing energy consumption capacity and improving shock resistance and shock absorption capacity of the structure.

Description

technical field [0001] The invention relates to the technical field of steel structures, in particular to an assembled novel anti-buckling support. Background technique [0002] The anti-buckling support damper is a support type damper with dual functions of ordinary support and metal damper. During small earthquakes, the supporting inner core remains elastic, which can provide lateral stiffness for the structure. During moderate or large earthquakes (ultra-large earthquakes), the inner core enters plasticity and dissipates energy through tension and compression yielding, which can effectively protect the main components of the structure. The anti-buckling support damper is mainly composed of two parts: one part is the inner core, which is used to bear the axial force transmitted by the structure; the other part is the outer restraint member, which is used to provide sufficient restraint for the inner core to prevent it stable. A gap is left between the inner core and the ...
